Application led April 7, 1,917. Serial No. 160.353.

T o all whom it may concern.'

Be it known that I, JOHN B. REYNOLDS, a citizen of t-he United States of America, residing at Toledo, Lucas county, Ohio, have invented new and useful Gear-Shifters, of which the following is a specification.

This invention relates to features of variable speed gearing control.

This invention has utility when incorporated in motor vehicles. especially for pedal actuation.

An embodimentyof the invention herein disclosed may be considered as progressive in itsl action for clutch pedal interconnection and operation, which clutch pedal operation control has 'as a factor the travel eX- tentof the clutch .pedal giving possibilities for neutral and reverse from any position.

he motor vehicle 1 may be provided with the floor 2, through opemngs 1n which `may project the service brake pedal 3 and the emergency brake edal 4. Between these .edals 3 and 4: is isposed the clutch Jedal raving the tread `5 rigid with the pedal ever 6 proJectingthrough the opening 7 in the floor 2 of the ear.

Pivotally mounted upon this clutch lever 6 is the auxiliary tread member 8 having the pivot bearing .9 and the projecting arm 10 normally held by coil sprmg 11 in the posi- Yin the frame 36.4 ber 36 forward. the element 37 maty leave tion shown in Figs. 1 and 5 to bring the tread 8 above the tread l5. This will cause the arm 10 to strike theiioor 2 outside the opening 7 thereby limitig the thrust'i'orward position vof the travel of the clutch lever G.

This clutch lever 6 is mounted on the fulcrum 12 carrying rigid therewith the arm 13 connected by link 14 to the lever 15 having the fixed fulcrum 16 to the fork 17 operable to pull the clutch member 18 against the resistance of springs 19, there by disconnecting the internal combustion motor driven Hywheel 20 from driving the shaft 21 extending into the variable speed transmission housing 22 for giving a plurality of speeds to the propeller shaft as a'ected by the operation of the reciprocable shift bars 24, 25, for producing respectively low and reverse, and intermediate and high driving speed connections.

Adjustably connected to the clutch lever 6 (Figs. 1, 5) is the link 26 extending to the arm 27 on the rock shaft 23 having the arm 29 provided with the link 30 extending rearward therefrom having the slot 3l. This slot 3] has loose connection with the pin 32 onthe reciprocable T-rember 33 guided in the control unit housing 34 having thc closure plate 35 (Figs. 2, 5, 6).4

. Mounted on this T-head 33 is the control member 36 reciprocable with the T-head and transversely movable thereacross as actuated by the toothed element 37 (Figs. 8, 9) disposed in said member or frame 36 and normally upwardly pressed by the spring 33 also coacting in the frame 36 for holding the element 37 in snug engagement with the straight or horizontal teeth 39 carried by the insert late h4l0 in the control unit hous- 'ing34- T 1e teeth in the element 37 extend in the direction of reciprocation or travel of the head or control device 33. 4

Staggered to be 'disposed a little torward of these horizontal teeth 39 and in the opposite member 35 of the control unit housing are the inclined teeth 41 (Figs. 3. 4) coacting with the inclined teeth 42 disposed in the frame 36 and normall; npwardly actuated by a spring 43 also coatting In the travel ot' the' memn the. teeth 36 while the teeth 42 still'eoact with the inclined teeth 41. This means that in this forward movement, the spring 38 at i truding its release at once thrusts element'37 to its upper limit in the member 36so that in the recover or rearward travel of the member 36, this element 37 due to the lift of the inclined teeth on element 41 will travel in the teeth one-tooth hi her on the member 40. Should this pul forward of the member 36 be sulicient to clear the teeth 42 from the teeth 41, the-spring 44 coacting from the controldevice or member 32, may

' act upon the member 36 to force the member y trunnion 49 laterally protruding from the frame or housing and connected by the link 50 to arms 51 loosely `mounted on pin.52 carried by the rearwardly protruding bracket 53 from the control unit housing 34. This arm 51 is the upper arm of a lever having the lower arm 54 connected by link 55 to the shift bar 24. e

This bar .48 is carried over plate 56 and under plate 57 in the unit housing 34'for free reciprocation. These plates 56, 57, have also associated .and spaced from Aplate 57, a similarv plate 58 mounted in guide ways 59 in the unit housing closure plate '35 and guide ways 60 in the unit housing 34. To prevent sliding of these plates 56, 57, 58 in these ways 59 and 60, the plates are provided with terminal projections or `ears 61 on each side at each end thereof.

In the region below plate 56 in the frame 34, 35 is the bar 62, having thelaterally protr-unnionr 63 connected =by link 64 with t e arm 54. Accordingly, inthe recover travel of the member 36 having its tongue 46 thrust this member 62 rearwardly, the lever 51, 54 is rocked tovdraw the shift bar 54 rearwardly-and actuate the transmis- -sion for reverse. This position for reverse throw is obtained by vrocking the auxiliary tread 8 adjacent the tread 5 so that the arm clears the opening 7 and the tread 5 has its throw full distance forward or so as to bring the arm`10 .through the floor 2. This withdraws the members 36 to such a position that the inclined ratchet '42 is pulled clear of the inclined tooth 45 to ride therebelow in the recover movement of the lever 6 as actuated the spring 19. y

Ign the thrusting orward of the tread 5 ig. 5) to bring the arm 10 say from" the point 65 to the point 66, the clutch 18 may Be released and the link 30 meantime -brought up to engage the pin 32.

Continued movement in this same sin le direction or thrust of the pin 9 forwar to bring the rarm 10 to position 67 pulls the control member 36 to a position that` the element 37 is clear of its teeth 39 and due to the action of teeth 42 coasting with the inclined teeth of the member 35, there is release of the member 36 so that the recover travel from the point 67 will result in bringing the ton e 46 in its recover travel into the recess 47u When the movement of the lever 6 picks ulp the T-member 33, 4this T-member 33 t rough its spring 68 disposedlongitudinally 1n the member 33, en agesthe pin 69 transversely thereof throug `the, frame or' housing 34. This pin 69reci'procable in the slots 70,71, of the housing or frame 34, 35, pulls the yoke members 72,73, (Figs. 5, 6) one along each side of the frame 34, 35, to embrace the protruding trunnions. Accordingly, in the forward thrust from position 66 to position 67, the yoke 72` en'lga es the rearwardly thrust trunnion 63, forward thereby disconnectingv t e trans mission from v`reverse,and A bringin it to neutral so thatin the recovertrave of the tongue 46 itworks idlyrin therecess 47.

vThe next th1ust..forward of the tread 5 (Fig. 5) 4from, osltion '66 4to .position 67 will cause ythe lilies lping up or progressive lift of the mem er 36 through the ratchets. The position 67 may be easily felt by the operator movingl the tread 5 for the pm 74 (Fig. 2) actuated by the spring 75 rides in the way 76,-of they l-rnember 33 offering resistance as rthe ratchet,A 37 ,leaves the teeth. 39. Accordingly,` recover will throw the tongue 46a ainst the bar 48 and oppositely shift the s iftbar 24into first speed forward. 4 The nextl thrustl forward ofthe tread 5 if past the resistance of the way 76 would result in the recover being at neutral. However with the thrust forward. being limited by the way 76, the recover will lcause the tongue 46 to Lengagethe `bar .77 having a trunnion thereon protrudinglaterallyof the frame 34 an'd connected; by'linjlr78to the arm 79 of.a.secondle;ver carried i, by the pin 52 on the o posite side of the bracket 53. This lever. 9,-is connected. by `link 80 to4 the .shift bar 25 and this travel :resultsul ing it 79 being rocked to neutral by `the yoke 73 and with the member 36 stepped up one more step, the reeovertravel of .the y ton ne 46 pushes the bar 81 rearwardlyand which bar has its trunnion vprotruding laterally of the frame 3410 engage linky 82 connected by the arm 83 rigid with the lever 79 to thrust the link 80 and its connected shift bar 25 forward therebv` shifting the caring in the transmission for third speed forward or hi h 4 It is accordingly seen this device is of sim le structure and one which ma be rea `ily and simply operated from a slngle control source in either direction from nentral or from any position to neutral, definitel determined by the feell from the way 76 ify just shifting is to occur, by full throw forward if to go to neutral and by the tilting of the auxlliary tread 8 if to go to reverse. There is precluded any second shifting for the yoltes 72, 73 pull to neutral any shifted connection before the recover travel of the pedal elects the ear shifting and this gear shifting is tim to `occur by the spring 84 before the clutch is set. The pull of these yokes 72, 73, toneutral is effected at once the member 33 is caused to travel but the continued or entire distance travel may not place a strain upon the yokes 72, 73 for the pin 69 has its travel limited by the guides 70, 71, notwithstanding the member 33 may continue its travel as permitted by the s ring 68'.
